The M4 Sherman Tank Early Production Model Set is a 1:35 scale plastic assembly kit of the U.S. Army's mainstay tank during WWII. The M4 Sherman medium tank series was the main U.S. Army armored vehicle during WWII and was instrumental in Allied victory. Over 55,000 variations were produced, making it the most widely produced tank of the war. The five major variants, from the M4 to the M4A4, were designated by their hull and engine. The M4 featured an angular welded hull and a Continental R975-C1 radial aircraft engine. Despite its power and proven performance, its high center propeller shaft gave the hull a tall profile. The suspension was a rugged and simple design known as VVSS (Vertical Volute Spring Suspension), with three units.
